We Got the Beat by The Go-Go's is featured in The Purple Piano Project, the first episode of Season Three. It is sung by the New Directions with solos from Brittany, Rachel, and Santana.

It is sung as an attempt to attract new members for the Glee Club, but the entire time through, no one seems to be interested, giving awkward and uncomfortable expressions. After the song, Jacob screams "Food Fight!" which leads to everyone in the cafeteria throwing food at the Glee Club members. Sugar Motta can be seen during the performance, to which she later attempts to join the Glee Club in The Choir Room.

After watching the performance, new members auditioned for the Glee Club (Sam and Sunshine in Season 2, Sugar in Season 3).

Something unexpected happened after the performance (No one—except for Sam and Sunshine—noticed their performance/Food Fight).

Both were the first song performed in the season.

Chris Colfer hurt his foot while dancing on a table during this number. He talks about it here.

This marks the first group number of Season Three with everyone in the Glee Club participating in it.

Errors

While Santana, Brittany, and Rachel are dancing/singing on the tables, they continuously change locations. Originally Brittany is in the middle with Rachel on her right and Santana on her left, but in the next scene, Santana is in the middle with Brittany to her right and Rachel to her left. They then go back to their original places in the next scene.

Near the end of the performance, there's a random line of Rachel saying "Whooo."
